Description

Technical Field

[0001] The utility model relates to the technical field of stator core production, in particular to a positioning rib pressure device in a heat dissipation groove for laminating stator cores. Background Art

[0002] The stator core is generally made of stamped silicon iron sheets stacked together. These silicon iron sheets are provided with slots on the outside. These slots mainly play the role of heat dissipation, noise reduction, magnetic field leakage reduction, and efficiency improvement. In order to position the stacked silicon iron sheets, prevent displacement and avoid the stacked silicon iron sheets from becoming loose, positioning ribs are generally pressed into the slots.

[0003] The positioning ribs are generally made of iron sheets and need to be pressed into the inside of the slot during the lamination process. The existing positioning rib pressure device cannot bend its two ends and needs to be manually hammered to bend the two ends of the positioning rib to ensure that the positioning rib is fixed in the slot. Hammering at both ends requires turning the iron core over, which causes the iron core to tilt and become loose and cracked. Therefore, a positioning rib pressure device is needed to pressurize and bend the two ends of the positioning rib so that it can be firmly clamped to the outside of the iron core. Utility Model Content

[0004] The utility model aims at the defects in the prior art and provides a positioning rib pressure-applying device for heat dissipation grooves used for laminating stator cores.

[0005] The utility model is achieved through the following technical solutions:

[0020] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0021] like Figure 1-3 The shown device is a positioning rib pressure device for heat dissipation grooves for stator core lamination, comprising a workbench 1, a first oil cylinder 2, a clamping platform 3, a positioning rod 4, a pressure assembly 5, a silicon iron sheet 6 and a positioning rib 7. The first oil cylinder 2 is installed on the inner side of the top of the workbench 1, the clamping platform 3 is fixedly arranged on the upper surface of the workbench 1, the positioning rod 4 is connected to the upper surface of the clamping platform 3, the pressure assembly 5 is installed at the telescopic end of the first oil cylinder 2, the silicon iron sheet 6 is arranged on the top of the clamping platform 3, and the positioning rib 7 is clamped on the outer side of the silicon iron sheet 6. The pressure assembly 5 includes a lifting ring 51, a mounting seat 52, a second oil cylinder 53, a sliding seat 54 and a pressure roller 55. The lifting ring 51 is fixed to the telescopic end of the first oil cylinder 2, the mounting seat 52 is fixedly arranged on the top of the lifting ring 51, the second oil cylinder 53 is installed on the back of the mounting seat 52, the sliding seat 54 is fixedly arranged at the telescopic end of the second oil cylinder 53, and the pressure roller 55 is movably connected to the inside of one side of the sliding seat 54.

[0022] Specifically, the sliding seat 54 is clamped on the inner side of the mounting seat 52, and guide sliders are provided on both sides of the bottom of the sliding seat 54. A sliding groove that cooperates with it is opened on the inner side of the mounting seat 52, a thread is opened at the bottom of the positioning rod 4, and a threaded hole that cooperates with it is opened on the upper surface of the clamping platform 3. The silicon iron sheet 6 is sleeved on the outside of the positioning rod 4, and a clamping groove that cooperates with the positioning rib 7 is opened on the outer side of the silicon iron sheet 6. A slot that cooperates with the positioning rib 7 is opened on the outer edge of the upper surface of the clamping platform 3. The thickness of the pressure roller 55 is less than the width of the clamping groove on the outer side of the silicon iron sheet 6, and the end of the pressure roller 55 is in contact with the outer side of the positioning rib 7.

[0023] In this embodiment, the positioning rod 4 is first connected to the threaded hole on the upper surface of the workbench 1 through the thread at the bottom of the positioning rod 4, and then the silicon iron sheet 6 to be stacked is sleeved on the outside of the positioning rod 4. The positioning rod 4 limits the sleeved silicon iron sheet 6 to ensure that it is neatly arranged and the heat dissipation groove on the outside is aligned. Then the pressure device used for stacking is pressed down, and the middle guide rod of the pressure device is clamped in the middle guide tube of the clamping table 3. The edge area applies pressure to the silicon iron sheet 6 to ensure the stacking effect. Then, the positioning rib 7 is inserted into the slot at the top edge of the clamping table 3, and the positioning rib 7 is bent upward so that it is clamped in the heat dissipation groove on the outside of the silicon iron sheet 6.

[0024] Furthermore, the second oil cylinder 53 is adjusted to push the sliding seat 54 forward until the pressure roller 55 can completely press the positioning rib 7 to the bottom of the heat dissipation groove. Then the first oil cylinder 2 is controlled to extend, driving the lifting ring 51 on its top to rise. Under the action of the pressure roller 55, the positioning rib 7 is completely pressed and fixed to the bottom of the heat dissipation groove. When the pressure roller 55 rolls to the top of the silicon iron sheet 6, the second oil cylinder 53 is controlled to extend, and the sliding seat 54 moves forward under the guidance of the inner groove of the mounting seat 52, so that the pressure roller 55 bends the top of the positioning rib 7, thereby ensuring that the positioning rib 7 is overlapped with the silicon iron sheet 6, completing the fixed installation of the positioning rib 7.
